Problems solved by technology

[0007] However, in seat belt retractors driven by electric motors, such as the seat belt retractor disclosed in Patent Document 1, the electric motor is driven while decelerating the seat belt in order to wind up and pull out the seat belt. The mechanism works to rotate the reel, so it is easy to generate vibration and noise

Abstract

This invention provides a seatbelt retractor capable of effectively suppressing occurrence of a vibration and a noise, a base frame (12) is composed of a first frame (16) for rotatably supporting a spool, and a second frame (17) to be attached to a motor vehicle body. The first frame (16) is composed of a pair of flat plate-shaped first and second supporting members (18 and 19), and spacing members (20, 21, 22, and 23) that couple the pair of the first and second supporting members (18 and 19). Further, the degree of the parallelization of the pair of the first and second supporting members (18 and 19) is obtained with high accuracy by the spacing member. Accordingly, an assembling accuracy for a spool can be improved and, thereby, a vibration and a noise caused by a rotation of the spool can be suppressed.

Description

technical field [0001] The present invention relates to a seat belt retractor for winding and pulling out the seat belt by a spool, which is used in a seat belt device installed on a vehicle such as an automobile and restrains and protects an occupant through the seat belt The technical field of a seat belt retractor, in particular, relates to the technical field of a seat belt retractor having a bottom frame rotatably supporting a spool and a seat belt device having the seat belt retractor. Background technique [0002] In the past, seat belt devices installed on vehicles such as automobiles prevented the occupant from getting out of the seat by restraining the occupant with the seat belt in an emergency when a large deceleration acts on the vehicle due to a collision or the like. The seat coasts to protect the occupant. This seat belt device is provided with a seat belt retractor that winds and pulls out the seat belt by a reel and prevents the seat belt from being pulled...
